No probs Kaz, glad to help confirm all the fitment issues with a compressor change to R134.

Original R12 compressor hose attachment plate removed, internals look clean, which is a good sign.

This compares the original '91-'96 compressor pulley alignment with the 471-1194 with the Rock Auto pulley assy. As can be seen, the Rock Auto assy is most definitely the later '97 offset, the belt run being closer to the compressor body.

New compressor & Rock Auto pulley attached to the original '91-'96 compressor mounting bracket. Photo doesn't really, due to fish effects but there is a definite mis-alignment.

Changed a few more air-con pipe seals, one of the old & new from the compressor hoses. Needless to say but they weren't in the best shape, so maybe the seals were the cause of the gas leakage.
